Abstract: In order to solve the evaluation problem of the rollback recovery fault tolerance in the distributed computing system, a rollback recovery fault tolerance simulation was designed. According to the structure of the rollback recovery fault tolerance scheme, the nodes task process of the distributed computing system was simulated by the discrete events. The simulation function of the rollback recovery fault tolerance was added in the application layer based on the network simulation software. The related structure, function modules and system parameters were introduced in the proposed simulation. Finally, the proposal was evaluated that the proposed simulation method is capable of the evaluation of the different rollback recovery fault tolerance scheme, and can be utilized to compare, improve and optimize the related fault tolerant algorithms.
